Hi, I'm trying to clock the CPU (MSP430F1611) to 8,000,000 Hz and I've run into some problems. Making the CPU to actually run at 8MHz was easy enough: DCOCTL = DCO0 + DCO1 + DCO2; /* 0xE0 */ BCSCTL1 = XT2OFF + RSEL0 + RSEL1 + RSEL2; /* 0x87 */ However, the UART1 stopped working. What I've got so far is: void uart1_init( unsigned int ubr ) { /* RS232 */ P3DIR &= ~0...

Followup to the message I posted the other week about Nokia 2260 LCDs for my Babylonian clock... the electronics are now working. The clock starts at 10:12:10 and ends at 10:13:08 in this video; you get to see most of the digits. It was slightly tricky to fit the 59 digits (at 32 x 22 pixels) into the 2K MSP430; I wound up making a set of sub-

Hi I would like to know if there is a guide, or someone could explain me, which are the steps to configure the MSP-FET430UIF (U80) in Ubuntu. I have the mspgcc compiler working, so I generetad a .o and .elf files from a basic source code, but I had no luck downloading the code to the MCU. I tried to use msp430-gdb but my software never worked. Is someone familiar to what Im doing? If someo...

Hi. I recently bought a msp-fet430u80 kit form TI and installed MSPGCC . Im used to make desings with PICs from Microchip but this TI MCU for me is really new and I think that I require a little bit of help, so if somebody just can advice me or answer this message, could probably help me a lot. My questions/troubles are: 1- Is there any C command guide for MSPGCC in where I can read how t...

Just got the USB version, eZ430-2013 Development tool, but It's not being rocognized by my PCs. Can anyone help? I just emailed TI, and while I wait for reply, thought I'ld ask here. I followed all installation instructions. When I plug it in USB, it's recognized as a MSP-FET430UIF JTAG device, then up pops the Hardware Wizard looking for a driver. I browse to where TI says to, but to no a...

Hi all, I?ve read the C code made by Xilinix to program a FPGA using an embedded microcontroller. The application is written to fit the 8051 and I have to port it into a MSP430f1232 to program a Spartan 3. In the application description it says it is easy to port the code into others microcontroller and it is only needed to change few functions in the file ports.c but my GCC refuses to com

Hello, When I toggle a GPIO on my MSP430 processor I have (or at least I think I have :) a clean understanding of what happens. I can relate the frequency of the toggling to the instructions used and the clock speed of the CPU. Nothing strange happens. The MSP430 runs the instructions below: /* Put 0xAA in the r15 register. */ mov.b #-86, r15 /* Write the contents of r15 on p...

newbie question: i've got a device (a radio control transmitter for model airplanes/helicopters) with 'f149. the pads for the jtag are present and we know the fuse is not burned. i'd like to read the contents of the flash (the firmware), make some edits, and upload the changes. does the mspgcc tool chain include a means to read the flash memory as well as a disassembler? can the IAR kick...

Anyone use this peripheral on a regular basis? I'm using an MSP430F2013 and trying to work out if it's possible to reclaim the -ve input pin for something useful. It seems to me that if I set P1SEL for that pin to GPIO mode, and set the SD16 into unipolar mode, I should be able to use the pin as an I/O, but it doesn't seem to be working properly. I'm not sure if that's because what I'm trying...

Hello: In several MCUs of the MSP430 family, during the bootstrap loader mode, the normal UART Tx/Rx transmit/pins aren't used. Instead, other pins are alloted for BSL transmit and receive. Would you know if the normal Tx transmit output pin goes in high-impedance mode during the BSL mode? Also, is there any register bit or pin offering information on "normal" vs "BSL" status? Th...

Hi, Texas have now released the ZigBee Z-Stack for free download. http://focus.ti.com/docs/toolsw/folders/print/z-stack.html Two versions are available for the 8051(CC2430) and MSP430. The problem for me is that even modest applications built for the 8051 can be over 100K in size even when fully optimised. This is worryingly close the the 128K flash limit on the CC2430. I'd like t...

Hi All, I am using a MSP430x4xx series controller. I have a doubt regarding the sharing of the LCD segment pins with I/O pins. I am using an LCD glass with 30 segments. The LCD controller of the device gives option of either setting S0-S31 OR S0-S27. Is there a way of setting S0-S29. This would save me two very valuable I/O pins. Thanks, Rohan

While working on my next book, I've built a small general-purpose prototyping board. This PCB is also intended to be useful for those projects where someone says "please prototype this" and it requires a micro that's only available in SMD. Here are the schematic and component placement:

i've got raw msp430 code extracted from a target device. i'd like to disassemble it. msp430-objdump requires the file to be in one of many file formats; e.g. symbolsrec, srec, tekhex, binary, ihex. i guess i need to write a converter, but i can only find a spec for the srec format. anyone know where i can find the spec for the other formats? or is there a converter that'll take as input m...

Hello: We are using two MSP430s that talk through an SPI interface. One MSP is the master, and the other MSP is the slave. Our problem is, the slave MSP is incorrectly receiving data. Through our logic analyzer and the IAR debugger, we can see that the master MSP is correctly receiving data and sending it out. We can also see that the slave is properly transmitting data. The proble...

Hello: Would appreciate comments/suggestions on methods for measuring the period of an audio-range signal with MSP430 (specifically MSP430F1612), with the highest resolution allowed by this MCU, especially if you have direct experience with that. Thanks. Marius Hancu
